JOS MALDA

Professor in Biofabrication in Regenerative Medicine

Prof. Jos Malda is a pioneering scientist in the regenerative medicine field of biofabrication. His ground-breaking work on the convergence of biofabrication technologies, such as extrusion-based and volumetric printing with melt electrowriting, laid the foundation for the creation of functional living implants with extraordinary/bioinspired structural complexity and high resolutions. With this, he has transformed the field of osteochondral regenerative medicine, and durable fibre-reinforced composite implants are now progressing towards the human and veterinary clinics. Malda leads and mentors an international and interdisciplinary team at the Regenerative Medicine Center Utrecht. He is also a leading educator and initiated the world’s first international master's degree in biofabrication (2015), as well as the first annual summer course in 3D printing and biofabrication (2013), and continues to direct both. He has received multiple international awards from the biofabrication and regenerative medicine communities. He was elected Presiden of the International Society for Biofabrication (ISBF) from 2014 to 2018. He currently serves as 2nd Vice President (2023-2025) of the International Cartilage Regeneration and Jointt Preservation Society (ICRS).
